To all whom it may concern:

Be it known that I, MARQUIS E. SWoR'rzEL,

a citizen of the United States, residing at Waynesboro, in the county of Augusta and State of Virginia, have invented a certain new and useful Electrically-Operated Pump, of which the following is a specification.

My invention relates to an improved electric pump, and it consists in the constructions, combinations and arrangements herein described and claimed.

tion of the pump cylinder and coiiperating parts; Fig. 3 is a horizontal, axial section of one of the heads of the pump cylinder; Fig. 4 is a vertical, axial section of the distributer; Fig., 5 is a rear elevation of the distributer; Fig. 6 is a face view of the removable head of the distributer, and Fig. 7 is a diagrammatic View of my invention.

Referring to the drawings, 1 indicates an automobile chassis provided with a spark coil 61 and an explosive engine 64.

The pump cylinder 1 is shown clamped in a split ring 14, which latter is provided with a base 2 for conveniently securing it in any desired position; a pump piston 16 being reciprocatingly mounted in the cylinder 1*.

The respective ends of the pump cylinder are closed by similar heads 3 and 4 provided with valve casings 5 and 6; said casings having inlet chambers 7 provided with supply openings 57*, and outlet chambers 7 pro-" vided with discharge openings 58.

-'The port 571 01. the inlet chamber is controlled by an inlet valve 9, which is yieldingly seated by a spring 12 engaging a shoulder on the stem 10 of said valve. The .port 58 of each outlet chamber is controlled by a discharge valve 9 having a stem l0 mounted in guides v11; said valve 9 being yieldingly seated by a spring 12 Contact bars18 and 18 are mounted, 'respectively, in the cylinder heads 3 and 4, and extend in position to be engaged by the pump piston 16.

formed with one integral head 38, and havpump piston 16 at'the ends of the latters stroke. The contact bars are yieldingly pressed inwardly by springs 24 in their supporting caslngs 19,. which latter are mounted in lnsulating bushings 20 in the cylinder heads; said insulating bushings 20 being provlded with annular end flanges adapted to' engage the adjacent faces of the cylinder heads. e

The casings, or guides, 19 are provided with heads 21 for engaging the inner end flanges of the bushings 20, andsaid guides are securely clamped in position by nuts 22 threaded thereon in clamping engagement with the outer flanges of said bushings 20.

A pa1r of motor solenoids, or coi'ls, '15 and 15 are mounted on the respective ends of the pump cylinder 1*, for actuating the The base 2 is provided with a flange 25 to provide a convenient attachment for the pump controller, which latter comprises a. frame 27 provided with arms 28 carrying'tubular guides 29 and 29 for slidably supporting the core 30 of auxiliary solenoid coils 31 and 31 mounted on said tubular guides. V

The solenoid 31 has its terminals connected, respectively, to the contact bar l8 and to one lead 68 of a battery, or other suitable source of electrical energy, 62; the terminals. of the solenoid 31 being connected, respectively, to the contact bar 18 and said battery lead 68.

A switch arm 33* of insulating material is secured to the solenoid core 30, and has conducting strips 33 and 33 secured on its opposite faces for engaging the contacts 34 and 34 spaced on a base 35 of insulating mate'- rial; The contact 34 is connected to one terminal 69 of the motor solenoid 15, and the contact 34* similarly connected to the terminal 7 O-of the motor solenoid 15*; the other terminals 57 and 67 of said motor solenoids being connected to the battery lead 56.

The base 2 is provided with a flange 26 for the convenient attachment of a. distributer, which comprises a cylindrical casing- 36 ing its open end closed by a head 50 secured thereto by bolts 52.

A spindle 41 is journaled in the head 38,

and carries a. rotary disk valve 40, which latter is yieldingly .maintained against the distributer head 50 by a spring 47. The

valve 40is provided with a port 48. adapted l to register successively with a series of ports 53 in the head 50; said ports 53 corresponding in number with the number of engine cylinders, or other devices, to which the distributer is applied, and being suitably connected thereto, as by pipes 54.

An arm 43 is rotatably mounted on the spindle 41, and has a spring-pressed pawl 45 pivoted thereon at 46 in engagement wlth a ratchet wheel 42 secured on said spindle 41; the solenoid core 30 being provided with a pin 32 engaging a slot 43 in said arm 43 v for actuating the latter upon reciprocation of said core.30.

The valve is provided with an annular groove 74 containing at one point a contact block 75 adapted to engage sprmg-pressed contacts 76;"ach contact 76 being mounted in a casing 77 screwed in an insulated bushing 78 in the controller head 50.

The supply openings 57 of the pump inlet chambers 7 are connected, as by pipes 71, with a carbureter, or other liquid supply, and thedischarge openings 58 of the pump outlet chambers 7 are connected by pipes 60 to ports 59 in the distributer casing 36.

The switch contact strips 33 and 33 are connected to the battery lead 68 by wires 68 and 68", respectively.

-When it is desired to operate my mvention, as for starting an explosive engine, the cut-out switch 65 in the battery circuit is closed and the electric current will pass through one of the motor coils 15 or 15, depending upon the position of the switch arm 43.

Referring especially to Fig. 7, when the switch arm 43 is in its left-hand position, a current will flow from the battery lead 56 through the motor coil 15, contact 34, switch contact strip 33, and wire 68 to the battery lead 68; thereby drawing the pump plunger 16 to the left and forcing the liquid from the adjacent end of the pump cylinder. Upon completing its stroke to the left, the pump piston 16 will engage the contact bar 18; thereby closing the circuit through the battery lead 56, wire 67, pump cylinder 1, piston 16, contact bar 18, solenoid coil 31*, and battery lead 68. In this positionof the parts, the solenoid coil 31 will be energized to draw the core 30 to the right and shift the switch strip 33 into engagement with the contact 34; thereby breaking the circuit through the motor coil 15, and energizing the motor coil 15 by closing the circuit throu h the battery lead 56, motor coil 15, wire 0, contact 34*, switch strip 33, wire 68, and battery lead 68. This will cause the motor coil 15 to draw the pump piston to the right and force-out the liquid previously drawn into the adjacent end of the pump cylinder. Upon completion of its stroke to theright, the pump piston 16 will engage the contact bar 18; thereby closing the circuit throughthe battery lead 56, wire 67, pump cylinder 1, piston 16, contact bar 18, solenoid coil. 31, and battery lead 68. In this position of the parts, the solenoid coil 31 will be energized to draw the core 30 to the left and shift the switch strip 33 into engagement with the contact 34; thereby breaking the circuit through the motor coil 15, and energizing the motor coil 15 by closing the circuit through the battery lead 56,

-motor coil 15, wire 69, contact 34, switch strip 33, wire 68, and battery lead68.

The above steps will then be repeated as long as the switch 65 of the battery circuit is maintained closed.

During such operation, the liquid will be discharged from both ends of the pump cylinder through the pipes 60 to the distributer casing 36, and the reciprocations of the solenoid core 30 will simultaneously swing the ratchet arm 43 to angularly advance the rotary distributer valve 40 sufficiently to bring the port 48 thereof successively into registry with the controller ports 53; thereby feeding the pumped liquid successively to the several cylinders of the explosive engine. This movement of the controller valve will shift the contact block 75 carried thereby successively into engagement with the contacts 76; thereby insuring proper timing of the ignition in the several engine cylinders.

' I have illustrated and described preferred and satisfactory constructions, but changes could be made within the spirit and scope of my invention.
